In Love's Territory (Love's Territory #1)
Lucy Evanson

As the only daughter in a wealthy Boston family, Katie Taylor has a comfortable home, good friends and servants to attend to her every whim. But when her father uproots her family and moves them to a farm in the Territories, her former life disappears forever. Soon she finds herself caught between the desires of two men: Edward, the wealthy businessman who has taken an interest in her, and Sam, the half-Sioux farmhand who has also kindled a passion within her. Now, when she least expected it, she finds herself without a guide in a brand-new land: the territory of love.
